The Pentagon is bleeding staff

Assistant Secretary Guy Roberts resigned effective April 2, according to a Defense official who asked to remain anonymous.

Roberts resigned a day before he had been scheduled to go before a House Armed Services Committee subpanel to testify on the Department of Defense (DOD) strategy, policy and programs for countering weapons of mass destruction. Deputy Assistant Secretary Christian Hassell appeared instead for the April 3 hearing, and no reason was given at the time for the change.

Roberts was in charge of the Pentagon office meant to “sustain and modernize the U.S. nuclear deterrent,” including missiles, submarines, and bomber aircraft, and “develop capabilities to detect, protect against and respond to” weapons of mass destruction threats. He was also responsible for ensuring “DOD compliance with nuclear, chemical, and biological treaties and agreements,” according to the department’s description of the office.

Roberts's departure adds to an already high amount of turnover at the Pentagon, which has been led by acting Defense Secretary Patrick Shanahan since the beginning of January, making him the department’s longest acting secretary in its history.

Owen West, assistant secretary of Defense for special operations and low-intensity conflict, is stepping down June 22, citing a desire for more time with his family, Task & Purpose reported earlier this week.

West in February told lawmakers that former Defense Secretary James Mattis was not wrong to disagree with President Trump’s plan to withdraw all 2,000 U.S. troops from Syria, an opinion that broke with the Trump administration.

Air Force Secretary Heather Wilson left at the end of May to become president of the University of Texas at El Paso.

Other senior DOD leaders who have recently left their positions include Robert Daigle, the director of DOD’s Cost Assessment and Program Evaluation office, who packed up in May to rejoin the private sector, as well as the Navy’s assistant secretary for energy, installations and environment, Phyllis Bayer, who in March submitted her resignation to "pursue other opportunities.”

Mattis announced his resignation in December following Trump’s surprise announcement that the administration would withdraw U.S. troops from Syria, and Pentagon spokeswoman Dana White, a top Mattis ally, left shortly thereafter.
